hmm no, unfortunately browser pdf viewer has no way to customize the name shown when using this technique.
you can try this that improves the mangled name a little more.
jsreport.renderAsync(request).then((res) => {
var contentType = 'application/pdf'
var dataView = new DataView(response)
var blob
var objectURL
try {
blob = new Blob([dataView], { type: contentType })
} catch (e) {
if (e.name === 'InvalidStateError') {
var byteArray = new Uint8Array(response)
blob = new Blob([byteArray.buffer], { type: contentType })
} else {
throw e
}
}
objectURL = URL.createObjectURL(blob)
var placeholder = document.getElementById('placeholder')
var iframe = document.createElement('iframe')
iframe.src = objectURL
iframe.style.width = '100%'
iframe.style.height = '100%'
// clear placeholder
while (placeholder.firstChild) {
placeholder.removeChild(placeholder.firstChild);
}
placeholder.appendChild(iframe);
Loading.hide()
})
